Border Paging Timing Adjustment for Wireless Network Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paging processes in cellular wireless communication networks often lead to increased paging-channel occupancy at border coverage areas, causing network overload and degrading performance, especially when border pages are initiated simultaneously with local pages within the last-known service area.
Innovation Solution
The proposed paging process determines the representative paging-channel occupancy of the border paging area and adjusts the timing of the border page accordingly, initiating it earlier if occupancy is low and later if high, to optimize the likelihood of locating the access terminal and manage channel occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If border pages are initiated simultaneously with local pages within the last-known service area, then the likelihood of locating access terminals is improved, but paging-channel occupancy at border coverage areas increases causing network overload
Solution Approach 1:
The patent applies dynamics by making the border page initiation time variable rather than fixed. The system dynamically adjusts when to initiate border pages based on real-time paging-channel occupancy conditions, allowing the paging process to adapt to changing network load conditions and avoid simultaneous initiation that causes overload
Solution Approach 2:
The patent changes the timing parameter of border page initiation based on paging-channel occupancy levels. By monitoring occupancy and adjusting the initiation time parameter, the system optimizes the balance between locating access terminals efficiently and preventing network overload at border coverage areas
2Quantity of substance
If border pages are initiated later to reduce paging-channel occupancy, then network overload is reduced, but call-setup time increases
Solution Approach 1:
The system changes the timing parameter of border page initiation based on occupancy conditions. When occupancy is high, initiation is delayed to reduce load; when occupancy is low, initiation occurs earlier to reduce call-setup time. This dynamic parameter adjustment optimizes both network load and call setup efficiency
Solution Approach 2:
The system uses feedback from paging-channel occupancy monitoring to adjust border page initiation timing. The occupancy information feeds back into the paging decision logic, allowing the system to adaptively control initiation time to balance load reduction with call-setup time minimization

AI summary
An access network may receive an incoming communication for an idle access terminal having a last-known location in a first service area of the access network. In response to receiving the incoming communication, the access network may determine whether the last-known location is proximate to a border between the first service area and a second service area of the access network. If so, the access network may define a border paging area encompassing one or more coverage areas within the second service area that are proximate to the last-known location. In turn, the access network may determine a representative paging-channel occupancy of the border paging area. Based on the representative paging-channel occupancy, the access network may then select a time at which to initiate a border page of the access terminal in the border paging area and then perhaps initiate the border page at the selected time.
